Description

  The present invention relates to a drug volatilizer in which a liquid drug having various volatility such as a fragrance and a deodorant is contained in a container and a core material capable of sucking and volatilizing the drug is immersed in the drug.

  In order to eliminate the discomfort caused by odors in rooms and automobiles and create a comfortable space, chemical volatilizers that volatilize fragrance naturally are widely used. Various chemicals such as gel, solid, and liquid are used in the chemical volatilizer, and the chemical volatilizer using a liquid chemical is generally contained in a container for containing the chemical and in the container. It is comprised with the core material which can suck up and volatilize the chemical | medical agent made. The core material is partially immersed in the drug, while the other part (volatilization part) can be exposed to the outside through the opening at the top of the container. The chemical is volatilized in the air at the volatilization part.

  An example of a chemical volatilizer using the above liquid chemical is disclosed in Patent Document 1. As shown in FIGS. 14 and 15, the drug volatilizer described in Patent Document 1 holds a container 100 that stores a liquid drug, a strip-shaped core material 102 that is stored in the container 100, and a core material 102. And the core material holding frame 101 to be configured. The core member 102 is connected to a pair of vertical plates 104, 104 provided on a pair of side frame members 103, 103 constituting the core member holding frame 101, and each side frame member 103 connected to a lower end portion of each side frame member 103.

  The drug volatilization container using the liquid drug can be reused by refilling the drug when the drug in the container 100 becomes small. However, at the time of reuse, the core material 102 that has completed the volatilization of the chemical is clogged by non-volatile components such as surfactants due to the volatilization of the chemical, and the wicking / volatilization function of the chemical is reduced. Therefore, it is necessary to replace the core material 102 with a new one.

  However, in the chemical volatilization container described in Patent Document 1 described above, since the strip-shaped core material 102 is wound around the core material holding frame 101, it takes time to remove the core material 102 from the core material holding frame 101. In addition, there is a problem that it takes time to attach a new belt-like core material 102 to the core material holding frame 101. Here, the above-described problem can be solved if a belt-shaped core member 102 is already attached to the core member holding frame 101 for replacement. In this case, the core member holding frame 101 is solved. However, since it is necessary to prepare a new one, there is a problem that it is expensive and not economical.

  The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a chemical volatilizer that can easily replace the core material with respect to the core material holding frame.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. The same or similar parts in the drawings are denoted by the same reference numerals and description thereof is partially omitted.

  FIGS. 1-3 has each shown the structure of one Embodiment of the chemical volatilizer based on this invention.

  The drug volatilizer 1 of the present embodiment has an opening in the upper part, a container 2 that can accommodate a liquid drug inside, and a core that is accommodated in the container 2 and can suck up and volatilize the liquid drug. A material 3 and a core material holding frame 4 capable of holding the core material 3 are provided. The upper opening of the container 2 is closed by a cap 5 so that it can be opened and closed. A core material holding frame 4 is rotatably connected to the cap 5, and the user can pull up the core material holding frame 4 from the container 2 by holding the cap 5. As the core material holding frame 4 is pulled up, the volatilized portion 31 of the core material 3 is pulled up from the inlet 21 to the outside of the container 2 and exposed. At this time, since the suction part 30 of the core material 3 is immersed in the medicine, the medicine sucked up by the suction part 30 of the core material 3 is volatilized outside the container 2 through the volatilization part 31 of the core material 3.

  As shown in FIGS. 1 to 3, the container 2 includes a cylindrical neck portion 20 having the opening on the upper surface and a hollow body portion 22 continuous with the neck portion 20. The body portion 22 includes a shoulder portion 23 that has a larger diameter than the neck portion 20. Examples of the container 2 include a transparent plastic blow molded product, but may be an injection molded product in addition to a glass product.

  A male screw portion 24 is provided on the upper outer peripheral surface of the neck portion 20. The cap 5 is fixed to the neck portion 20 of the container 2 by screwing the male screw portion 24 with the female screw portion 50 provided on the inner peripheral surface of the cap 5.

  A pair of projecting portions 25 and 25 projecting inward are integrally provided on the lower inner peripheral surface of the neck portion 20. Each protrusion part 25 is provided in the position which opposes, and each protrudes in the thickness direction of the core material 3, and opposes the front surface and rear surface with the largest area of the volatilization part 31 of the core material 3. As shown in FIG. Accordingly, an opening having a substantially rectangular shape in plan view along the outer shape of the volatilization portion 31 of the core material 3 is formed in the neck portion 20 by the two protrusion portions 25. The opening serves as an inlet 21 when the core material holding frame 4 holding the core material 3 is pulled up or inserted into the container 2.

  Each protrusion 25 holds the core material holding frame 4 in an upright state when the core material holding frame 4 is pulled up. That is, when the core material holding frame 4 is pulled up, the front end surface of each protrusion 25 comes into contact with a part of the core material holding frame 4 (the outer surface of each side frame member 40 described later) holding the core material 3. The core material holding frame 4 is held in an upright state by sandwiching the core material holding frame 4. Further, since the core material holding frame 4 is sandwiched by the protruding portions 25 protruding from the inner peripheral surface of the neck portion 20, a space is generated between the core material holding frame 4 and the inner peripheral surface of the neck portion 20. Therefore, the core material holding frame 4 can be tilted at least in the front-rear direction (the thickness direction of the core material 3) with each protruding portion 25 as a fulcrum.

  The lower surface of each projecting portion 25 is an inclined surface that is highly inclined inward. Moreover, the upper surface of each protrusion part 25 becomes the inclined surface which inclines low toward the inner side, and each protrusion part 25 has a taper-like shape as a whole. The portions that are continuous with the top surfaces of the upper and lower surfaces of the protrusions 25 are respectively smooth curved surfaces.

  In addition, in this embodiment, although each protrusion part 25 is integrally provided in the neck part 20 of the container 2, it is not necessarily restricted to this structure. For example, each protruding portion 25 may be detachably provided in the form of an inner plug with respect to the inner peripheral surface of the neck portion 20 of the container 2.

  A cylindrical boss 51 is provided on the inner bottom surface of the cap 5 so as to protrude from the inner bottom surface. The tip of the boss 51 is equally divided, and a plurality of (for example, three) engaging claws 52 are provided. A stepped portion 53 is provided on the outer surface of each engaging claw 52. The boss 51 can be fitted into a fitting hole 43 provided in the connecting portion 42 of the core material holding frame 4 to be described later, and each of the engaging claws 52 is elastically deformed inward so that the boss 51 is fitted into the fitting hole 43. Then, the core material holding frame 4 is rotatably connected to the cap 5 without coming off in the axial direction by hooking the stepped portion 53 of each engaging claw 52 to the lower surface of the connecting portion 42. .

  As shown in FIGS. 4 to 6, the core material holding frame 4 is formed of a flexible material such as plastic, for example, and has a pair of left and right plate-like side frame members 40 extending downward. 40 and a horizontal plate-like upper frame member 41 that connects upper end portions of the side frame members 40 to each other. A connecting portion 42 is integrally provided at the center of the upper frame member 41, and a fitting hole 43 is provided at the center of the upper surface of the connecting portion 42. The upper end portion of each side frame member 40 is formed to be wide, and L-shaped opening and closing members 44 and 44 for opening and closing each side frame member 40 are integrated with the upper end portion of each side frame member 40. Is provided.

  In a state where each side frame member 40 hangs downward, the distance between each side frame member 40 is set to be slightly smaller than the thickness of the volatilization portion 31 of the core material 3. Thus, the core member 3 is held by the core member holding frame 4 so that the volatilization portion 31 is sandwiched between the side frame members 40 and the suction portion 30 is suspended from each side frame member 40. Each side frame member 40 is elastically swingable with the upper end portion 40A serving as a fulcrum. For example, the side frame member 40 applies a thumb to the upper surface of the cap 5 (shown in FIG. 1) and each L-shaped opening / closing member 44. By placing the index finger and the middle finger on the bottom surface 44A of each side and pressing each opening and closing member 44 toward the cap 5 (the direction of the arrow P shown in FIG. 4), the lower end portions 40B of the side frame members 40 are mutually connected. Separate (open operation). Thereby, the volatilization part 31 of the core material 3 can be inserted between the side frame members 40. And if the press with respect to each opening-and-closing member 44 is cancelled | released, each side frame member 40 will reset (close operation) to the state which hangs down to the original downward direction by the restoring force by elastic deformation, and will volatilize the volatilization part 31 of the core material 3. Hold it. Further, after the core material 3 is used, similarly, each opening / closing member 44 is pressed toward the direction of the cap 5 (direction of arrow P shown in FIG. 4) to open each side frame member 40. Thus, the holding by the side frame members 40 with respect to the core material 3 is released. As a result, the used core material 3 can be easily detached from the core material holding frame 4.

  In the present embodiment, the entire volatilization portion 31 of the core material 3 is held by the core material holding frame 4. When the core material holding frame 4 is inserted into the container 2, each side frame member 40 is sandwiched between the projecting portions 25 of the container 2, so that each side frame member 40 is opened and closed by each opening / closing member 44. Operation is restricted. Therefore, the core material 3 cannot be removed from the core material holding frame 4 unless the core material holding frame 4 is pulled out from the inlet 21 of the container 2.

  The lower end portion 40B of each side frame member 40 is formed wide, and one side edge portion in the width direction is bent inward to provide a first bent portion 45. A predetermined region from the lower end portion of the first bent portion 45 is bent into a “<” shape so as to follow the shape of the lower surface of the volatilization portion 31 of the core material 3, and a part of the lower surface of the volatilization portion 31 is formed. The supporting support surface 46 is constituted. The first bent portion 45 supports one side surface of the core material 3 sandwiched between the side frame members 40, and the support surface 46 restricts the core material 3 from being displaced downward. Yes. Further, a part of the upper part of each side frame member 40 is formed to be wide, and one side edge in the width direction is bent inward to provide a second bent portion 47. Yes. The second bent portion 47 supports the other side surface of the core member 3 sandwiched between the side frame members 40.

  The lower end portion 40B of each side frame member 40 is integrally provided with outward engagement projections 48, 48 protruding from the plate surface at the center of the outer surface. Each engaging protrusion 48 is provided so as to protrude in the direction of the protruding portion 25 which becomes a stepped portion inside the container 2. Therefore, when the core material holding frame 4 is pulled up when the chemical volatilizer 1 is used, each engagement projection 48 is hooked on and engaged with the lower surface of each protrusion 25 of the container 2. Thereby, the core material holding frame 4 is prevented from coming off, and the core material holding frame 4 is prevented from coming out from the inlet 21 of the container 2.

  An insertion guide portion 48A is provided at the lower edge of each engagement protrusion 48 so as to be inclined downward from the outside toward the inside. The core material holding frame 4 is once pulled out from the inlet 21 of the container 2 for refilling the medicine or replacing the core material 3, and then inserted when the core material holding frame 4 is inserted into the container 2 from the inlet 21 again. Each engagement protrusion 48 is easily bent inward by the presence of the guide portion 48 </ b> A, so that each engagement protrusion 48 easily gets over each protrusion 25. As a result, the core material holding frame 4 can be easily inserted into the container 2.

  A plurality (three in the illustrated example) of protrusions 49 are integrally provided on the outer surface of each side frame member 40 at equal intervals in the vertical direction. Since each protrusion 49 engages with the upper surface of each protrusion 25 provided on the inner peripheral surface of the neck 20 of the container 2 when the core material holding frame 4 is pulled up, the core material holding frame 4 is in the container 20. It is designed not to inadvertently fall inside. Thereby, the core material holding frame 4 can be held at a predetermined height position.

  As shown in FIGS. 7A and 7B, the core 3 includes a substantially rectangular parallelepiped suction part 30 and a volatilization part 31, and the suction part 30 and the volatilization part 31 are continuously integrated. It has the form which was made. The core 3 is entirely composed of a fiber layer (not shown) that is excellent in the effect of sucking and volatilizing a liquid drug. The fiber layer can be composed of a fibrous material such as natural fibers such as plant fibers or pulp, synthetic fibers such as rayon, polyester, PET (polyethylene terephthalate), PP (polypropylene), or mixed fibers thereof. . In particular, a nonwoven fabric manufactured by an airlaid method, a needle punch method, a spunbond method, a spunlace method, or the like is suitable, but other layers such as a woven fabric and a knitted fabric may be used. In addition, you may provide the coating layer comprised by the thin rayon, for example on the surface of the said fiber layer.

  In this embodiment, the suction part 30 is formed so that the width | variety becomes narrower than the volatilization part 31. FIG. Thereby, when the core material holding frame 4 is accommodated in the container 2, the suction part 30 is folded, and when the core material holding frame 4 is pulled up, the suction part 30 is extended. Each can be easily deformed (see FIGS. 1 and 2). The suction portion 30 is set to a length that can reach the inner bottom surface of the container 2 when the core material holding frame 4 is pulled up, and can suck up the medicine to the end. Further, the volatilization part 31 is formed to be wide so that the chemical is easily volatilized in the air when the core material holding frame 4 is pulled up. In addition, in this embodiment, although the width | variety of the suction part 30 is made narrower than the width | variety of the volatilization part 31, the width | variety of the suction part 30 and the volatilization part 31 may be the same magnitude | size.

  Next, the usage method of the chemical volatilizer 1 having the above-described configuration will be described.

  In the chemical volatilizer 1 having the above-described configuration, in the state where the cap 5 is fixed to the neck 20 of the container 2, as shown in FIG. 2, the core 3 has the suction part 30 and the volatilizing part 31 in the liquid chemical. I'm immersed. On the other hand, as shown in FIG. 1, when the cap 5 and the neck portion 20 of the container 2 are unfixed and the cap 5 is pulled up from the container 2, the core material holding frame 4 is pulled up from the inlet 21 of the container 2. Thus, the volatilization portion 31 of the core material 3 is exposed to the outside of the container 2. Thereby, the chemical | medical agent sucked up by the suction part 30 via the volatilization part 31 is volatilized in the air. At this time, a plurality of protrusions 49 are provided on the outer surface of each side frame member 40 of the core material holding frame 4, and when each of the protrusions 49 pulls up the core material holding frame 4, the container It engages with the upper surface of each projecting portion 25 provided on the inner peripheral surface of the second neck portion 20. Thereby, the core material holding frame 4 is not inadvertently dropped into the container 2, and the core material holding frame 4 can be held at a desired lifting height. Therefore, the user can change the surface area of the volatilization part 31 exposed outside, and can adjust the volatilization amount of a chemical | medical agent.

  In addition, when the core material holding frame 4 is pulled up, the engaging protrusions 48 of the side frame members 40 are hooked and engaged with the lower surface of the projecting portion 25 of the container 2, so that the user mistakenly holds the core material holding frame 4. Even when the core is excessively pulled up, the core material holding frame 4 is prevented from being inadvertently pulled out from the inlet 21 of the container 2.

  On the other hand, when the chemical in the container 2 becomes small due to the volatilization of the chemical, or when the volatilization performance of the chemical deteriorates due to clogging of the non-volatile component such as a surfactant in the core 3, After pulling up the material holding frame 4 until each engaging protrusion 48 engages with each protruding portion 25, the material holding frame 4 is tilted forward or backward (in the thickness direction of the core material 3 indicated by the arrow X1 or arrow X2 in FIG. 1). Thus, the core material holding frame 4 can be easily pulled out from the inlet 21 of the container 2. That is, in this embodiment, each engaging protrusion 48 of the core material holding frame 4 is provided so as to protrude in the thickness direction of the core material 3 that can tilt the core material holding frame 4. When the holding frame 4 is tilted, the engagement protrusion 48 on the tilted side is displaced inward and downward to disengage from the protrusion 25. Here, when the core material holding frame 4 is further lifted in a state in which the core material holding frame 4 is tilted (that is, in a state where the engagement protrusion 48 and the protruding portion 25 are disengaged), Only the engaging protrusion 48 that engages with the protruding portion 25 of the container 2 on the opposite side receives the inward pressing force by the reaction force from the protruding portion 25. Thereby, since the side frame member 40 is bent by elastic deformation, the engaging protrusion 48 on the opposite side to the inclined side is displaced inward, and the engagement with the protruding portion 25 is released to easily get over the protruding portion 25. Thereafter, the other engaging projection 48 on the inclined side is easily pulled out of the inlet 21 of the container 2 by overriding the protruding portion 25 by pulling up the core material holding frame 4. Is possible.

  Thus, in the present embodiment, the core material holding frame 4 can be easily removed from the inlet 21 of the container 2 by a simple operation of pulling up the core material holding frame 4 while tilting the core material holding frame 4 in either the front-rear direction. Therefore, the refilling of the medicine and the replacement work of the core material 3 can be easily performed. Further, the container 2 and the core material holding frame 4 can be reused by replenishing the container 2 with a new medicine or replacing the core material 3 of the core material holding frame 4 with a new core material. It is.

  Further, when it is desired to replace the core material 3 of the core material holding frame 4 with a new core material, the core material holding frame 4 is pulled out from the container 2 and then each opening / closing member 44 is moved using, for example, an index finger and a middle finger. Press in the direction of the cap 5. Thereby, each side frame member 40 opens and the state which clamps the core material 3 is cancelled | released. As a result, the user can easily remove the used core material 3 from the core material holding frame 4 without touching the medicine, and the core material 3 can be easily replaced with the core material holding frame 4. be able to.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of the chemical volatilization device which concerns on this invention is not limited to above-described embodiment. For example, in the above-described embodiment, the side frame members 40 of the core material holding frame 4 are arranged one by one so as to face the front surface and the rear surface having the largest area of the volatilization portion 31 of the core material 3. Two or more plural pieces may be provided, and the number of the side frame members 40 provided on the front side and the rear side of the volatilization part 31 may be different. Moreover, in above-described embodiment, although the side frame member 40 is made to contact the front surface and the rear surface of the volatilization part 31 of the core material 3, and the core material 3 is clamped, it is a side by the both sides | surfaces of the volatilization part 31 of the core material 3. You may comprise so that the frame member 40 may be contacted and the core material 3 may be clamped, and also the side frame member 40 is arranged so as to face each of the front surface, the rear surface, and both side surfaces of the volatilization portion 31 of the core material 3. And you may comprise so that the side frame member 40 may be made to contact the above-mentioned 4 surface of the volatilization part 31, and the core material 3 may be clamped. In this case, a pair of side frame members 40 provided on the front and rear surfaces of the volatilization part 31 are opened and closed by the opening / closing member 44, and a pair of side frame members 40 provided on both side faces of the volatilization part 31 are provided. Thus, the opening / closing operation is performed by another opening / closing member 44.

Therefore, the used core material 3 can be easily detached from the core material holding frame 6. . Therefore, the user can easily replace the core material 3 also by the core material holding frame 6 shown in FIGS.

  In addition, also in the core material holding frame 6 of this embodiment, the entire volatilization part 31 of the core material 3 is held by the core material holding frame 6, and the core material holding frame 6 is inserted into the container 2. When being done, each side frame member 60 is sandwiched between the projecting portions 25 of the container 2. Therefore, the core material 3 cannot be removed from the core material holding frame 6 unless the core material holding frame 6 is pulled out from the inlet 21 of the container 2.

  Furthermore, FIGS. 11 to 13 show other embodiments of the core material holding frame. 11 to 13 includes a pair of left and right side frame members 80, 80 facing each other, and front and rear frame members 81 and 82 that are perpendicular to each side frame member 80. It is formed in an enclosure shape. The volatilized portion 31 of the core material 3 is accommodated in the accommodating space B surrounded by the side frame members 80, the front frame member 81, and the rear frame member 82, and the bottom surface U of the accommodating space B is opened. ing. In addition, the width of the accommodating space B (distance between the side frame members 80) is set slightly smaller than the thickness of the volatilization part 31 of the core material 3, and the volatilization part 31 of the core material 3 is compressed. Thus, each side frame member 80 is sandwiched.

  In the illustrated example, each side frame member 80 is composed of one vertical frame 83 and a plurality of horizontal frames 84 that are parallel to each other. The front frame member 81 and the rear frame member 82 are configured by a plurality of side frames 85 that connect the ends of the opposing horizontal frames 84 of the side frame members 80, and the side frames 85 allow the storage space B to be accommodated. Both side surfaces of the volatilization part 31 of the housed core material 3 are supported.

  The horizontal frames 84 at the upper ends of the side frame members 80 are connected to each other by a horizontal plate-like upper frame member 86, and a connecting portion 87 is integrally provided at the center of the upper frame member 86. A fitting hole (not shown) is provided at the center of the upper surface of the connecting portion 87, and the boss 51 provided on the inner bottom surface of the cap 5 is fitted into this fitting hole, thereby providing a core material. The holding frame 8 is rotatably connected to the cap 5 without coming off in the axial direction.

  In addition, an engaging protrusion 88 that protrudes outward is integrally provided at the lower end of the vertical frame 83 of each side frame member 80. Since each engaging protrusion 88 is provided so as to protrude in the direction of the protruding portion 25 which is a stepped portion inside the container 2, when the core material holding frame 8 is pulled up when the chemical volatilizer 1 is used, each engaging protrusion 88 is provided. 88 is hooked and engaged with the lower surface of each protrusion 25 of the container 2. Thereby, the core material holding frame 8 is prevented from coming off. In addition, the lower edge of each engagement protrusion 88 is formed so as to be inclined downward from the outside to the inside, and constitutes an insertion guide portion 88A. In the drawing, 89 is a protrusion that can engage with the upper surface of each protrusion 25 provided on the inner peripheral surface of the neck 20 of the container 2 when the core material holding frame 8 is pulled up.

  In the core material holding frame 8 shown in FIGS. 11 to 13, when the core material 3 to be held is to be replaced with a new core material, the core material holding frame 8 is removed from the container 2 in the same manner as the above-described embodiment. After the extraction, the core material 3 can be easily removed from the core material holding frame 8 by extracting the core material 3 from the opened bottom surface U of the accommodation space B. Therefore, the replacement work of the core material 3 can be easily performed also by the core material holding frame 8 shown in FIGS. In the illustrated example, the front frame member 81 and the rear frame member 82 are provided at both ends of each side frame member 80. However, the front frame member 81 or the rear frame member 82 is provided only at one end, The other end may be opened. Thereby, the volatilization part 31 of the core material 3 can be extracted from the bottom surface U or the front surface (or the rear surface) of the storage space B or stored.

  In addition, also in the core material holding frame 8 of this embodiment, the entire volatilization portion 31 of the core material 3 is held by the core material holding frame 8, and the core material holding frame 8 is inserted into the container 2. When being done, each side frame member 80 is sandwiched between the projecting portions 25 of the container 2. Therefore, the core material 3 cannot be removed from the core material holding frame 8 unless the core material holding frame 8 is pulled out from the inlet 21 of the container 2.
